- UNITED 51,'z4aese JOHN D MAIER, or oHAaLEsrown; MARYLAND' i i REAMER FOR sifroKEns7 irns firApplication fiIedjFebruary 17, 1928. Serial N'o. 255,005. p

This invention relates to a reamer for pipes, the general object vof the invention being. to

providex a reamer,`so1ne of the blades vof, which are collapsi-ble sothat the device -will i 5 be'flat when said bladesare folded against other blades, thus enabling the device tobe placed in the pocket 'of the user When not vin use, with means whereby the foldableblades will automatically assume a position at right-V i angles'to Vthe other blades when the device.

is placedin the bowl of a pipe and turned.v

Another object of the invention is to make' the device of tapered shape with 'the blades having curved edges so that the device rwill fit various sizes of pipes.

A still further object of the invention is y to provide the device'with pivoted members whichican be swung outwardly and used to remove foreign matter' from the mouth pieces i 2,0 of pipes and from 'the bowls of the pipes.

. .f This invention also consists `in certain other features of constructionand in the'combination and arrangement ofvthe several parts, tor-be' hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

'In describing my lnvention in detail, ref-' erence will be had rto the accompanying drawings wherein like characters denotelikel l Or corresponding parts throughout the sev- Figure 5v is a view! of one of the foldableA` blades.

Figure 6 is al ure 1. i i i Figure 7 i is a view of a modification, showinO' the foldable blades formed integral.

section on line 6-6 of Fign these* drawings, the numeral 1 indicates` the body of the device which isformed' with a tapered lower part having its edges slightly curved to form the. stationary blades 2, ther edges of which are b'eveledr and the upper part` is enlarged to form a heador handle 3,v this handle having the projecting wings for form'- ing. a 'hand grip so that the device can be asily turnedv by the thumb and finger of'one The bodyis provided with a centrally arrangedlongitudinally extending groove 4 and the grooved part is cut transversely. to form the straps 5, these stl'aps being bent outwardlyv in an opposite directionffrom the grooved: portion'so (that they rwill form, with parts of the grooved portion, hinge barrels; The bottom of the groove between the straps is PArTgFFICE cut longitudinally and the edges of the metal f adj acent 'the cut are bent in. opposite directions to form the xfla'ng'es 6; The foldablev i Wings are shown at 7, these wings also having curved cutting edges and .their inner edgesare' cut to,v form the recesses 8 and the inner edgeof eachfoldable blade is formed With a pair of tongues which are bent over to7 form the hinge barrels 9. The foldable blades areplaced one on each side of the body,

'with the'hinge harrels of 'one blade engaging the. recesses of the other blade and said' barrels enter the Opening left by the flanges'. These barrels are in alignmentx with the barrels Lformedon the body so that a hinge pin so* '10 can be .passed 'through the barrels to'l hingedly connect the foldable bladesiwith the I i body, asi'shownithe drawings.

g Thus itfwill' be vseen that the blades '(Tcan.

befolded against the'istationary blades of the' 'body so 'that the'device'will have a'flat'form and thusfcan bereadily placed in'fthe pocket of the user andV this will ralso enable the de- Vices to be packed in small boXes as they will occupylbut littlel space. when so 'folded .VVhen i the device'isplacedfin the bowl of ar pipe,

as shown in Figure, and 'given a slight turn on the foldable bladesby the walls' of Vthe pipe will cause said bladesfto swing outwardly.v at rightangle's to the body, asishown' in'Figv. ure 3,-so that all fourb-lades will engage the walls of the bowl andfthus lscrape'the same. When the 'foldable blades are inv this position, theyi will bear against the flangesl (i 'and vin a clockwise direction, the friction eXertedv iob the parts 11 atV the inner edges of the foldable blades will bear against the pin 10 so that said-blades are firmly held in operative position. The flanges 6 also act to strengthen the stationary blades.

Figure 4 shows the blades formed with indent-ations 12 in their cutting edges, the indentations of one blade being in alignment With those on the other blades so as to prevent an auger effect taking place whenthe device is rotated in the bowl of 'a pipe, Which would occur if the indentations Were offset as this oifset arrangement Would form spirals so that the device would act as an auger or screw and work itself into the bowl so that there Would be danger of splitting the bowl.

Figure 7 shows the blades 7' formed integral, the blades being connected together by the straps 5' Which form the hinge barrels. A slot 15 is formedbetween the lower ends of the blades so that one of them `may be passed through the Opening in the body in assembling the device. The blades are offset as shown.

I also pivot a pair of arms 13 to the head part of the body, one arm being on one side and the other on the other side, with one arm of greater Width than the other, With the not in use, the device Will be flat sothat itV can be carried inthe pocket. By placing the device in a pipe boWl and turning it in aV clockwise direction, the foldable blades Will move outwardly to a position at rightangles to the body and thus provide a four-bladed reamer. Y v

The head or handle part 4 also forms a reamer for the'top of the boWl. In this con-` nection, `the device is reversed and the top part of the head is placed in the pipe and acts as a guide While the upper edgestof the Wings act to ream the top of the boWl.

It is thought from the foregoing description that the advantages and novel features of my invention Will bereadily apparent.

It is to be understood that I may make changes in the construction'and in the com-4 bination and arrangement of the several f parts, provided that such changes fall Within the scope ofthe appended claims.

lVhat I xclaim is i 1. A pipe reamer of the class `described comprising a flat body having av dovvnwardly .taperillg lower part providing a painof `flanges on the body 1,74e,ose

cutting edges and said body having a centrally arranged longitudinal groove therein With portions of the grooved part slotted, a

hinge pin in the grooved part and a pair of foldable blades hingedly connected With the pin, said blades automatically moving outwardly into operative position When the det vice is placed in a pipe boWl and'turned, and

ing lengthwise along the slot, a member 'having a portion passing through the slot With its centralportion hingedly connected with the pin, the side edges of this member tapering downwardly to provide a pair of cuttingedges, said member automatically moving outwardly to a position at rightangles to the body when the device is placed in av pipe boWl and turned, and stop means forpreventing the member from moving beyond a position at right angles to the body.

3. A pipe reamer of the class described comprising a flat body having a downwardly tapering lower part providing a pair of cutting edges, the central portion of theibody having a longitudinally extending slot therein, a hinge pin connected With the body and passing lengthwise along the 'slot, a member having a portion passing through theslot With its central portion hingedly connected With the pin, the side edges of this member tapering downwardly to provide a pairvof cutting edges, said member automatically moving outwardly to a position at right angles to the body'When the device is placed in aV pipe boWl and turned, and stop means for preventing the member from moving beyond a position at right angles to the body, such means comprising oppositely extending formed by hending the metal left by the slot outwardly from 7the body. i i i In testimony Whereof I affix my signature.
